4.4Sound Spectrum Analyzer meters sound noise level (SPL - amplitude in decibel) and detects sound frequency spectrum in real time (RTA) using FFT. The analyzer is very easy to use and offers a lot of useful features: high RTA refreshing rate and frequency spectrum resolution, adjustable sound noise level (SPL) amplitude scale (up to 150 decibels), RTA peak hold function, flat reference line, local peak frequency... Sound analyzer can detect audio on 3 separate channels. User can later compare noise level (SPL - dB) and frequency spectrum charts between the channels.It also includes a frequency generator with noise option, which helps to analyze the frequency response of audio system. Audio Input/output can be adjusted to Internal, AUX or Bluetooth. However, all I/O options and combinations do not work on all devices. Sound frequency analyzer can be accurately calibrated for each frequency band separately.
